Answer:
The total years of sleep = 25.05 years
Explanation:
Given total time in minutes = 3.95 x 10^7
Now convert the total time in hours = (3.95 x 10^7) / 60 = 658333.333 hours
Now covert the total hours into the day. Since a day has 24 hours so divide the total hours by 24 = 658333.333 / 24 = 27430.5555 days.
A person sleeps 8 hours a day, so total hours of sleep = 8 × a number of days.
A person sleeps 8 hours a day, so total hours of sleep = 8 × 27430.5555 days.
Thus, total sleeping hours = 219444.444
Now convert it into a number of years.
Convert total hours into the day and then years.
Number of days = 219444.444 / 24 = 9143.5185 days.
Now covert the total days in to years = 9143.5185 / 365 = 25.05 years
